Episode 1 "The Importance of being E...est"

From tvguide.com

The reality series shakes things up as it launches this fifth edition. The 16 latest castaways are marooned on Koh Tarutao, an island off the coast of Thailand in the Andaman Sea. “It's a foreboding environment,” says executive producer Mark Burnett of the site, which is teeming with pythons and king cobras in its dense jungle. The former penal colony is also known for its steep limestone cliffs. As for changes, Burnett promises that all of the challenges are entirely new. He also says that “the game starts off in a whole new way.” While he declines to elaborate, it looks like this version initially begins with all-male and all-female tribes.

Hmmmmm, the Importance of being Earnest by Oscar Wilde immeadiately springs to mind, but MB wouldn't have left those letters out of the title unless her had a very good reason.

Very interesting, Fluff. My guess from your list would be "Earliest" as tribe designation and/or camp location and/or the first boot may be dependent upon who is the first or last to arrive somewhere or finish a task.

Well, I would say I have to agree with you there LG.
Take a look at the supposed tribes according to vidcap anaysis from posters at "sucks".
It seems that one team is heavily populated with the younger, stronger contestants.

It was kind of disappointing to he how the show started.
We were supposed to "never be able to guess" what the twist would be.
I've seen many people throw the "pick your own teams" angle thrown out as a theory, the only thing I didn't see posted correctly was who the captains would be.
